[kai19960504]

Hi All,

I have successfully used notify to transfer 1 byte of data.

Now I want to try to transfer 1 array but I have a problem as shown in the figure.

Here is my project,please help me to debug.

Lab07_BLE_CustomService_TS200.zip

IDE : SEGGER

SDK : v17.1.0

Best regards,

Kai

I suspect you need to go into ble_lbs_init() and find where the .max_len is set. I believe it is by default set to 1 (byte), so if you want to support longer packets you can for instance set it to 20.

Hi Kenneth,

Thank you,I miss this setting.

It did work after changing .max_len

Best regards,
